Blue trousers are probably the easiest thing to match shoes with, anything from black to brown to tan can look good. The most versatile choice would probably be brown oxfords, I don't know which ones to suggest for <$100 though.

Any ideas for a pair of shoes that can go for any occasion.
maybe brown oxfords?
brown clarks desert boots?
my budget is only around 100 dollars

thanks for the help![/QUOTE

personally, I prefer brown over black...but black is ok too....
now back to your $100 budget..tough call...not sure if there are any SF approved items here for that budget...depending on your size, B&S or ebay...

from what I've learned here on SF, contact AE shoebank @ Retail Brookfield <brookfield@allenedmonds.com> give 'em your size and they will send a list..I realize that it may be over your budget, but if you squeeze in the extra dough, it is a better investment in the long run.....Next thing you know, you are dying for CJ, EG, Aldens...... damn SF
